Study on preparation and properties of PVC film modified by rare earth
The transparent PVC films were prepared by tape casting. In the process of preparation, rare earth nitrate, as a kind of modifier, was added to the solution of PVC and THF. These PVC films were tested after being crosslinked by ultraviolet light. It is found that the mechanical and physical properties of all the PVC films modified by rare earth nitrate are greatly enhanced.

012. Melt-phase behavior of collapsed PMMA/PVC chains revealed by multiscale simulations
Single- and double-chain models of three stereoregular polymers, iso- and syndiotactic poly(methyl methacrylate) and isotactic poly(vinyl chloride), were extensively simulated using systematic coarse-grained (CG) potentials. It was found that, in vacuum, all of these long chains collapse in a two-stage process from their fully extended configurations into coils, and the two chains in each double...

Phase structure of PVC/MBS blends by small angle x-ray scattering
The phase structure of blends consisting of polyvinyl chloride
(PVC) and methyl methacrylate–butadiene–styrene graft copolymer (MBS) are
examined by small-angle-X-ray scattering (SAXS). The interface layer thickness (),
correlation distance (ac), and interface layer specific surface area (Ssp) are
calculated using Debye–Bueche’s statistical theory. The results show tha...

Influence of the diameter of CaCO3 particles on the mechanical and rheological properties of PVC composites
PVC composites filled with CaCO3 particles with different diameter (about 40, 80, 500, 25000 nm) were prepared by using a single-screw extruder. The mechanical and rheological properties of the composites were investigated. The results showed that while the diameter of CaCO3 nanoparticles was smaller, the mechanical properties of composites were higher. By adding 40-nm CaCO3 nanoparticles into the...

CPE对ASA/PVC合金冲击断裂行为的研究
关键字：ASA，PVC，CPE，冲击
本文在ASA/PVC共混体系中添加第三组份增韧剂CPE，制备了ASA/PVC/CPE三元共混复合材料。并通过仪器化冲击试验机表征了材料的冲击性能及断裂过程的能量分布。结果表明，合金冲击强度随着CPE含量的增大而逐渐增大，在15份时达到最大。冲击断裂的能量与裂纹引发阶段和裂纹扩展阶段有关。

共混过程中MAH对PVC色泽的改善
关键字：MAH PVC 色泽
PVC的稳定性能包括PVC的热稳定性和色泽稳定性。PVC加工过程中，稳定剂除了要有一定的热稳定时间外，还要有较好的颜色。由于PVC加工过程中受热脱HCl形成共轭多烯烃，往往导致PVC发生颜色变化。我们通过共混，使马来酸酐（MAH）中的双键与PVC降解形成的共轭双键发生Diels-Alder加成反应，阻断共轭多烯烃的增长，改善PVC加工过程中的色泽。

增韧PVC透明树脂的理论和实验
关键字：透明树脂，PVC，增韧
透明树脂在塑料工业中占有重要的地位，广泛应用于日常生活的各个领域，如片材、板材、扭结薄膜、异型材等。聚氯乙烯（PVC）是世界总产量仅次于聚乙烯的第二个大品种通用塑料，它在机械稳定性、耐化学药品性和阻燃性等方面具有优异的性能，但由于其抗冲击性、热稳定性及加工方面的不足大大限制了其应用范围。为进一步拓展其应用领域，已有多种抗冲击改性剂开发上市。
